The Death’s Head Roach, Blaberus craniifer, is named for the skull-like pattern on the “pronotum”. I generally try not to present ‘bugs’ as 'creepy,’ but the kids definitely enjoyed meeting one of these for Halloween.
Surprising fact: like many roaches, these are “ovoviviparous:” they give live birth!
Don’t worry, they’re not native (nor could they survive if they escaped) in the USA, with the exception of Key West, Fl. They mostly live in Central America and Mexico.
#1845 - Laxta rieki - Trilobite Roach
Banjup, Perth.
Males are winged with a wide thoracic shield, but the females are wingless and can cling very securely to the wood and bark they’re hiding under. The best-known species is L. granicollis, but that’s probably because all but one of the other 13 species were named and described in 1992.
